James devoted most of his epistle to our tongue. As proverbs says, angry words stir up strife, trouble. Our tongue is one of the smallest members of our body. But no one can control it without the Holy Ghost. And the bible says out of the abundance of the heart the mouth speaks. So, when your mouth speaks and boast of great things, it sets on fire trouble. Trouble out of the pits of hell. How can the mouth bless and curse at the same time? Can fresh water or salt water come out of the same fountain? This is why we must submit ourselves to the Holy Ghost. He will be able to control our tongue. Then we will be able to speak wisdom from above, that is pure, peaceable, gentle, easily entreated, full of mercy, without partiality and without hypocrisy. Only God can control your tongue. James 3.
